NaOH + HCL -> Nacl + H2o
1 gram of Naoh reacts with 1 gram of HCL
so 199 g reacts with 199g
By adding catalyst e.g. mno2,vanadium oxide
by increasing the temperature if it is an exothermic reaction
by also decreasing if it is an endothermic reaction
2.5X20=50g
50g should be the right answer
Mass=volumeXdenisty.
Electron affinity is defined as the change in energy (in kJ/mole) of a neutral atom (in the gaseous phase) when an electron is added to the atom to form a negative ion. In other words, the neutral atom's likelihood of gaining an electron.
The difference in cardio-respiratory fitness and cardio-respiratory endurance is a very thin line. Cardio endurance the physical fitness of a person is measured.
It is termed as the ability of a person's body to send nutrients and oxygen continuously to all parts of the body when a physical activity (including lungs and heart) is done for a prolonged period of time. While cardio-respiratory fitness can be called as the fitness of the lungs and heart of a person's body.
